.To all whom it may concern.-

Be it known that LLUTHER C. CROWELL. a1

' citizen of the United States, residing at Brook .lyn, countyof Kings, and State of New York, have invented certain new and useful Improvements in Folding and Staple-Binding Delivery Mechanism for Printing-Machines,

fully describedand represented in the following specification and the accompanying draw:

ings, forming a part of the same; v

These improvements relate 'pri marily to n stapling mechanism-for binding together plicate'd webs or sheets delivered thereto'preferably from any machineproducing them, and especially from rapidly operating printing machines by which such 'webs or sheets are printed and rapidly delivered.

More particularly'these improvements re date to that class of such stapling mechanisms in which the staple inserting means travel in the direction of the material to be stapled, and move to and frorn'the inserting point-preferably rotatively in the opera- 1mm of carrying. the staple into relative position to the material for its insertion therein,

1 and co-operate with a clinching device in settingthe'staple in," on, or near, the ultimate binding line of plicated webs or sheets,-thus producing a bound book like product without necessitating that the moving material, shall.

means causingsaid tool to travel onward,

preferably rotatively,, from.[the staple forming point in carrying the'staple into position relat-i ve to t he mate rial for its insertion therein.

The invention also includesyarifous other improvements, constructions, combinations of parts, mechanis'ms'a'nd devices, all of which arefparticularly hereinafter pfoi'nted' outv in theclaims and, explained in the course of the latter figure.

which the invention is or may be practically embodied and carried into eflect,a ready understanding of which description and claims will be aided by reference to the accompanying drawings, in wh-ich- Figurelis an end elevation of so much ofthe following detailed description of the modein deliverymechanism .of a printing machine as is requisite to illustrate these improvements;

Fig. 2 is a side elevation of the same. Fig. 3 is asectional elevation of the rotative carriers ors'upports and the mechanisms, tools or devices, which they support. Figs. 4., 5 and 6 are' perspeceive views partly in section ofsome of the stapling tools or devices in three positions of their operation. Fig. 7 is a face or end view, Fig. Sis asectional elevation, and Fig. 9'is a front elevation of such tools, the forming anvil being shown in section in the Fig. 10- is a face view of the staple leg clinching device. Fig. 11 is an end elevation of so much of a delivery apparatus of a printing machine having stapling mecll ,anis'ms connected with it, as is necessary to Fig. 12 is'an enlarged sectional elenation with the delivery mechanisms of a Web printing machine or .machines,.it may pre-' '-.1iminarily be stated that such a printing ma- .chinemay be of any rotary or other construction that rapidly delivers its printed product, and preferably such a machine as per fects the product by printing uponth'e opposite sides thereof, as for instance, the printing machine shown in my aforesaid application.-- sucna. printing machine, in one of its more approved constructions, may include. turning bars for associating sheets or webs and will preferably embody a longitudinal folder as F, overwhich longitudinal folder the printed material is carried and plicated or given a longitudinal told, as may be desired,

in any suitable manner, preferably substantially as is described in Patent No. 331,280.

So, also, the printing mechanism may be a combination of several machines, all delivering their product over a roller or cylinder, either directly to the stapling mechanisms, or to-one or more longitudinal folders. If the paper, printed upon in such a machine is maintained in the; form of a web until it passesoverthe longitudinal folder, it will act.

as its own carrier, as is well understood,suitable guiding rollers being provided for its onward passage. If, however, the paper operated upon is divided transverselyinto sheets before passing onto the longitudinal folder,

it will beprovided withoa taped orother path-'- way for carrying the sheets on ward. If from a'double wide printing machineor machines, the sheet or sheets, 'web or webs, whether split or not, are transferred laterally one upon another, by bars, there will be a plication by association. If the webs or sheets frem twoor more independent printing machines are brought together in passing over a roll or cylinder, there will also be plica'tionv by association. In either of the above cases the sheets or webs may be split; by a slitter in order that the bound products may be cut attheheads. '3 V Q -I n passingover'a longitudinal folder of substantially the construction: and operation fshown'in my previous patents, preferably .such a one as is illustratedin-my Patents Nos. 331,280 and 492,760, the webs or sheets will be folded or'plicated longitudinally, and

I if there be a multiplicity of printing mech anisms delivering their webs or sheets to the longitudinal folder, there willbe two or more such sheets or webs superimposed on the longitudinalfolder, all of which will be simultaneously plicated by folding; if,, however, there be arranged for -co-operation with the longitudinal folder a slitter as 26 eith er arranged to slit the sheets orwebs before, dayweb, sheets will be formed by transverse sev.-

ingxor'after. their passage over said longi tudinal folder, the sheet or sheets, or web or webs will be divided longitudinally. and

hence 'be plicated I by association, except.

where the 'slitter operates during or after the folding, when the plication will be partially or wholly by folding, aswill be readily understood. When the material is 'run in the cranes, as is hereinafter described. a I

In the'principal embodiment of the invention herein shown, the rotative carriers or supports which carry or s'upport all qf the travelingstapling mechanisms, tools or devices, are shown as cylinders O, D, which cylindrical form of carrier is, for some reasons, a preferable construction, as among other uses, it

is sometimes desirable that a portion or all of their surfaces may act to carry the material onward. These cylinders or supports are geared together and to the other rotative mechanisms so that all concertedlyrotate with which longitudinal folder may be constructed" appropriate speed,'and theywill prbferably be geared with the printing machine so asto move therewith in cooperative precision. As shown in Figs. 1 to 3, these cylinders are of double size, that is, theyhave a circumference equal tosthe'. intended length'of two sheets,

which is sometimes preferable and especially where the sheets are-small, and hence they are each provided with a duplication of mechanisms. Thus the carrier or support D is provided with two sets of stapleinserting means oppositely arranged therein,-the stocks for the holder or presenting tool 41 and the inserting tool or driver 44 of which are respectively marked HIH and I, I; and the carrier or support .0 is shown as provided with a corre spending number of staple leg clinching devices, which consist-of metal" blocks U, V,"

that are attached to the carrying cylinder or support 0 by means of screws, which blocks extend to the periphery of v the cylinder and are provided with properlyshaped grooves 16, 17 that are preferably inclined on all sides to 'adaptthem ltnntepeive, and their bottoms are curved.-;to;capac itate them to appropriately turn the staple'legs toward each other or bend them down onto the plicated webs on sheets;

' Considered longitudinally there are shown two sets of staple inserting means and clinchi'ngdevices, but any number of sets may be are desired as binders.

. For convenience and simplicity of the mechanisms the cylinder or support 0 also carries two cutting blades 20, 21 that respectively cooperate with cutting slots 22, 23 provided in the cylinder or 'supportD; also with sets" ofsheet impaling-pins 24, 25 which engage the leading ends of the plicated webs or sheets employed according as more or less staples 3 and carry the same onward within the range 7 of action of folding mechanisms, which latterv are rotative double folding blades 48,49 and "50, 51 that co-operate with folding rollers 52, 53, and have portions removedas indicated at 11 to enable'them to pass the stapling devices,

From thedelivery rollers 30,31, throl l'- setter. the plicated material pas'ses,'itri'sl onward" between thecylinders, carriers or supports 0, D and in such onward passage, as will presently' be described, its plies are united together by staples on transverselines a sheets severed by transverse cuts through the codistauce apart, which lines are the ultimate binding lines of completed products. When. the cylinders or carriers G D, are provided with devices therefor-these sheet lengths are operative action of the blades 20, 21.an'd slots 22,-23,and' the leading ends of each set of sheets or webs from which they are to he severed, are held and carried onward by'means of the impaling pins24, 25, which withdraw at suitable intervals to permit a rearward movement of the le'adipg portion of the sheets or 'webs,necess'ary to thef-olding operation of' of the material, their insertion therein,"'and the clinching down of'their legs therein, while thejrna'terial and the active tools or devices are moving onwardin like directions, with an appropriate speed of travel suited to that at which the printing is performed and the. material is delivered will now be explained.

. The wire from which the'staples areto be formed is delivered from-'spools, as 8.0, and 7 carried within the range of action of the tools or mechanisms supported by and associated 3e e "by bracket 79) and its cutting die 18, so as to travel of the staple tools, mechanisms or .de-

with carrier D, by meanstof a wirefeeding mechanism attached to the frame X' of the machine, and overhanging-said carrier. There is a wire-feeding mechanism for each set of the tools, mechanisms or devices, considered in their longitudinal arrangementin the cyl-v inder, carrier or support D. Each'consists of a pair of feeding rollers {6, 9, between which the. wire passes and is frictionally driven for-. ward from a reel or spool 80,.and protruded through atubular guideblock 77 (supported be. projected within'the range of rotative vices supported by the carrier or support D.

The larger roll 6, against which bears the roller 9, is fast upon and is driven by means, of a worm wheel 73, thatisl rotated bya worm 76. The worms 76 are fast upon a *shaft 78. which is so geared with the carrier D, by means of wheels 74, 7 5, that the feeding action of the rollers 6,9 is capacitated during each half revolution of the cylinder, carrier or support D to deliverastaple length of wire through the die 18 of the guide'block 77 and protrude, the same across'the pathway in which the stapletools in a stock, H or I- of the carrier or support D rotatively travel, and be-;

neaththe forming anvil 40.' See Fig. 2. The

forward ledge 40f one arm 43 of thetwo armed traveling staple holder or presenting tool, acts as a shearing cutter-in passing the cutting die 18 and severe a staple length of wire, which is thus. detachedgwhile within the range of action of a forming anvil'40 which isprefe'ri ably curved over the top of the carrier or sup-- portD and hung pendent from the framework. This anvil 40 has a'width equal to the inside length of the crown or head of, the sta ple to'beformed, a thickness preferably at leastequal to the length of the staple legs, an under curved surface, the forwarder main portion of which is preferably coincident with the periphery of the cylinder or=support D ;v and it is sustained in properrelation to the moving staple tools, devices. or mechanisms, bymeans of rods 81, 82, that are secured to the 1 framework, upon which it is made adjustable by means of set screws 83.- It is additionally preferably widened at its rear end so as to form sidewise projections or wings 7, 8, that. guide the'incoming wire and provide a support for the entire wire length delivered beneath it, which support extends such a distance forwardfrom its rear endas to fully cover the wire feeding point, asshown in Fig. 4. This widening is advantageous, but as it is not essential it is shown as omittedin Figs-14 and 15. The rearward portion of the anvil 40 is shaped on its under side so as to form av wedge like pathway 10 or entrance beneath it for the rotatively moving staple tools or devices. The

-- 1 forward end of this anvil 40, where the'staple on; and preferably this wedge like guide will bejcontinued downward so far that the trav-' .eling. staple will leave its endat the moment .when' the clinching plete. 7 I Y 6f'the staple inserting means the holder or of the staple legs iscompresentingtool and the inserting tool or' driver, reciprocate in carrying stocks as H I- "which are shown as fast upon the shaft of the cylinder or support D and thus cause it to move therewith and rotatively carry the sta ple inserting means to and from the point where the staples are to be presented to and finserted into the material.

presenting tool 41 is forked toprovide two arms 42, 43 between whichv slides the insert- .ing tool or driver 44 and the forwardedge 4 Tot the arm 43 acts as a shearing cutter in cooperation with the outer or month end of the wire guiding slot or die 18 of the block 77,

and hence in passing the same acts as a'shear, to sever a staple length of wire, which isthus detached while within the range of action of f the forming anvil 40. The'side of the arm 43, immediately rearward of the cutting edge 4, is removed-in angular forui as at 14 to provide space for the outward movement-of the new [wire length while the holder or presenting tool 41 is passing thewi re feeding point. The, in-

.sertin'g tool or (1 river 44 is provided on each side" ICO The holder or used. In this example the two arms 42, 43

of the holder or presenting tool 41 project from a hollow shank that slides to a slight extent in the carrying stock H or I, in which'it is seated upon a'spring withinsaid shank that bears upon-the foot of the stdckand constantly presses it outward; and the inserting tool or driver 44, embraced by the arms 42 43 of the holder or presenting tool41, not only slides in the guiding channels, but is provided with "a shaft like stem the upper end ofwhi'ch plays in a central guide slot in the hollow shank of the holder and the inner end\ of which plays in a similar guide slot cut through a collar projecting inwardly from and through the base or inner head of ,the stock H or Loutside of which base or head this stem is screw threaded and; provided with a nut for adjusting the extent of its outward throw; and this tool or holder 44 is constantly pressed outward to hold a staple protruded, cause the inserting of the same, and p it is,capacitated to be retracted during the inserting operation and thus enabled to assume a position to aid in thejformation of a new staple, by means of a spiral spring that is coiled about its stem and made to hear at one end upon a shoulder on said stem and at the other upon a collar,like support'that is fast to and projects within the carryingstock H or I and encircles said stem. These parts of the arms 42, 43 of the holder-or presenting tool 41 and that part of the inserting tool or driver44,-which are in advancebf the wire bending or stapleforming portion of them, are recessed or slightly beveled so as to admit of their unobstructed movement past the protruded wire, (see Fig. 3) but those parts of the holder and mandrel which are rearward of their wire bending or staple forming line, are extended. outward so as to sweep, in their rotative travel, into the plane occupied by the protruded wire, the arms 42, 43 passing close to the underfaces of the guiding wings 7, 8, of the anvil, and the inserting tool or driver 44, all passing close to the under, face of the curved bending anvil 40. These, parts thus come into contact with astaple length of the protruded wire, which wire length will, while momentarily supported between the 1 outer faces of the armsof the moving holder or presenting tool, inserting tool or driver, and the, under faces of 'thewings 7, 8, be sev ered by thdacti'onofjthe cutting edge 14 in passing thevdie' 18 "of-l the wire guiding block- 77. This detached staple length of wire will then be carried onward in a circular pathway by the rotative traveling movement of the holder or presenting tool and inserting tool' ordriver. During this travelingor onward movement, the arms 42, 43, of the holder maintaining theirposition of outward protrusion-by means of the efficient power of their supporting spring,- will prhgressively overlap and travel close to the sides of theanvilf40 while the wedge like pathway or receivingend 10 of. the curved forming anvil 40, will, as the wire length is carried over it, operate to press inwardly the central portion of the said wire length which has entered beneath it, thus forcin its cehtral or crown portion and the insertin tool or driver beneath 'it, upon which it rests, within the guiding channels cut longitudinally into the facing sides of the arms 42, 43, of the holder. As the wedge like portion" 10 of the curved anvil thus presses the wire length and" inserting tool or'driver inwardly,the central portion'of said/wire length, whichis to constitute the crown or head of the staple, then held or clamped between the outer face of the inserting tool or driver and the inner face of the anvil, will, while remaining straight or horizontal, be carried bodily within the arms of the holder or presenting tool, during which operation theopposite ends of the wire length, which "primarily rest over the ends of the arms 42, 43, will be forced into the longitudinal bending guiding channels 2, 3 in the inner faces of the arms of the holder, said wire ends being thus forced or bent outward or at right angles to the central crown or body portion of the'wire length, to convert them into staple legs. In this operation, the arms 42, 43 act as bending arms and in conjunction with the forming anvil 40, these wire ends or staple legs will progressively descend into said channels until the thickest orthat part of the anvil 40 which is nearest to the carrier D is reached, when the staple will have been formed, at wh-ich'time' it will be inclosed on all sides and be completed, as in Fig. 6, ready for insertion. The staple thus formed is seated within the holder or presenting tool wlthits head or crown resting upon the insorting tool or driver 44 andhas its legs em- 1 braced-in the channels 2, 3 of the arms 42,43

of the holderand extending therefrom more or less according to the size and strength of the wire, which holder,'as it moves'rotatively from the wire receiving point to the point of insertion for the staple, acts as conveying or transferring means for the wire length and staple formed therefrom. According to the length of the protrusion of the arms of the holder beyond the periphery of the carrier D, they will, in approaching the setting point, come into contact with the plicated material as they traverse the wedge shaped exit end or forwardrtermination of the forward end of the anvihand the relation of parts is such (viz': the substantial radialarrangementf of holders H, 1,) that 'the' staple legs are presented to or directed toward the stapling point or line of ultimate folding or binding of said material in such a plane that the insertion thereof will then be accomplished by a forward movement, substantially at right angles to the path of travel of the material,

and as the material, the carriers 0, D and the staple presenting and inserting tools or mechanisms they carry, then preferably all move concertedly onward to the actual staplesetting point,-which preferably is where the carriers C, D run nearest together, the ends of I the arms 42, 43 of the holder or presenting tool 41 will press the material toward and anism,-it will be apparent that the products eral sheets having one fold upon their bindshown in ing line, or of packs of the latter suitably stapled together. t

From the foregoing, it. will be apparent from slight consideration, that where two or more printing mechanisms are employed, the association of their webs, whether split or not, either run directly together between rollers, or transferred laterally for association, will cause a plication suitable for the stapling operation. Although these illustrations have not included means'for stapling the webs longitndinally, such are understood to be con- I tained herein in like manner as so described in connection with my aforesaid application. While any suitable wire feeding and wire length cutting mechanisms or devices'may be employed, an approved means for cutting the staple lengths from the bodyof the wire is Figs. 14 to 17. vInstead of depending upon the shearing action of one side of one of the arms or holder or presenting tool in coaction with the mouth of the wirecondnit or die 18, there is provided a separately acting cutter which is a swinging blade 33 pivoted to a standard34, that is. supported from theguide block 77. This cutter depends before. the die 18 on the end of. the guide block 77 so as to be-in shearing contact therewith, and the side of the arm 43 of the holder or presenting tool 41 is recessed so as to enable it during its onward, movement to pass the'cutter 33. The cutter is provided near its lower extremity with an angular cutting jaw 35 through which the wire length is fed out-- ward, and this recess isrprovided with a tappet 36 which, during such onward movement engages the lower end ofthe cutter and thus swings it forward and upward to causeits cutting jaw 35 to sever the wire length, a spring 37 operating to quickly retract the cutter into a position admittihg the immediate outward feeding movement of the wire for the protrusion of a new staple length. The curved anvil 40 though shown herein as supported above and inageneral sense coincident with the periphery of the carrier D, might be let into said carrier so as to extend within or protrude into the periphery thereof.

This requires some modification of the parts,'}

as will be apparent, but such a structure is not claimed herein, it being mentioned to indicate the scope of the invention embodied in this improved mechanism. A stationary anvil having an under surface curved may presenting,

be set eccentrically with carrier D or curved pathway of the traveling staple holder or presenting tool and thus provide a guiding the rearward or; entrance end of' said anvil with the wedge like formation 10. i

A prominent or characteristic feature of the staple forming, and holding, carrying or and inserting or driving, tools or devices, is that the. principal tools or devices shall travel length is received to another point to which the staple, that is intermediately formed in the periphery. of the I .70 surface in the formation of e the staple which is tantamount to providing from one point where the .wire

connection with an anvil, shall be carried for insertion and, be inserted into the material. This is shown as a rotary movement, but as the path of-travel v cillation, and such a travel may also-be peris an are, it may be an 0S formed by what is known as a four way nio- 7 tion in connection with a straight anvil, and hence the term traveling used in-connection with the tools is to be takenin a broad sense as including such and indicating the broad scope of the claims.

The traveling holder or presenting tool operates as a staple forming tool while passing over a portion of the anvil, but it will be 0bserved that that s that part of the anvilis reached which is its limit of projectiontoward said tool, and since the formation of the staple is then complete and it is held within the arms of the holder, it is practical to omit anyforward extension of the anvil beyond it, since the staplewill then be held in the arms of the holder or presenting tool in position for onward carriage and presentation to the material, by reason of the limit of the outward movement of the holder or presenting tool 41 that is determined bya stop screw which enters through the side of the stock H, or I and has an extension that projects into an elongated slot in one side of its hollow shank, and also by reason ofthe limit of the outward movement lot the driver or inserting tool 44, that is determinedby the stop nut adjustable on the threaded inner end of its shaft like stem, whichf nugabuts against the inner e'nd of the stock H or I; but it is preferable to extend the anvil as near as possible to the staple setting point. t

It is to be observed from the foregoingdescription that the staple insertihg'means consists generally ofa staple holder or presentiug tool which holds or presents and some times guides the made staple so that its legs shall properly enter thematerial, and a tool or driver which acts to insert or compel the entranceof the staple into the material. .It is to be understoed however, that the staple holding'or presenting tool may also act as a tool or driver for inserting the staple into the material to bestapled, notwitsmnding that in co-operation with a forming anvil it also motion or movement function of it ceases when j performs the function of a bending tool in I the operation of formingstaples, and that it buckling or bowing.

The term sweep longitudinally, as used 4 in the claims with respect to the forming movement of the holder or presenting tool, means that said tool moves or travels lon2itudinally along over said 'anvil and at the same time carries with it the wire lengths the ends of which are thus progressively bent to form a staple as it is .carried or swept onward by the tool.

By the termcurved anvil? as used in the claims, is meant an anvil, or similar part, c o.

operating with the staple holder; or presentingtool having that face curved between -Whlch and the tool the crown of. thestaple is held during the staple forming operation; and, it ma Y be during the carrying of the staple from the forming point -to the setting point.
